WordPress Developer (Part-time, Contractor Role)

Cornershop Creative is looking for a developer with advanced WordPress core skills and experience, along with extensive experience in Engaging Networks customizations (development and onboarding) and similar platforms, while also containing extensive experience working with REST APIs and integrating various platforms, including Salesforce and other CRMs. This position requires strong knowledge in PHP, React, common javascript libraries, and AI assisted coding (Claude Code, Codex, etc.).

Our ideal candidate is a hard-working, curious self-starter comfortable working independently with little supervision, but also able to work as part of a team that includes developers, designers, and content strategists. They will also be comfortable meeting directly with clients to discuss project strategy, goals, and solutions.

Core Responsibilities

• Leverage existing REST APIs and worker processes to build client-facing integrations, including runbooks and troubleshooting notes.
• Configure, customize, and extend WordPress membership/e-commerce plugins and payment flows.
• Develop and customize Engaging Networks pages, form handlers, and API integrations.
• Build or integrate enterprise search solutions (Elasticsearch/Algolia/Solr).
• Write automated tests, CI/CD pipelines, and monitoring/alerts for production systems.
• Lead client-facing technical calls and produce clear technical documentation.

Must-Have Skills & Tech

• Strong backend dev experience (5+ years) — PHP (WordPress), and at least one of Node.js or Python for services/ETL.
• Deep WordPress experience: PHP 7/8, WP-CLI, Advanced Custom Fields, custom post types, hooks, plugin development. Comfort configuring membership plugins (MemberPress, Paid Memberships Pro, WooCommerce + memberships).
• API design & implementation: REST, JSON, OAuth, webhooks, idempotency, rate-limits.
• Data integrations: building scheduled jobs, CSV/JSON/XML transforms, data mapping, error handling.
• Experience with Engaging Networks (development + onboarding) or similar platforms and their APIs.
• Enterprise search configuration: Elasticsearch, AddSearch, or Solr — index design, relevance tuning, facets, security filtering.
• SQL & relational DBs (MySQL/Postgres); comfortable writing performant queries and schema design.
• Use AI-assisted development (e.g., GitHub Copilot / CodeX / Claude Code to speed work: leverage code generation for scaffolding, API clients, mappings, and test generation — with mandatory human review for correctness, security, and maintainability.
• Adopt modern acceleration practices augmented by LLMs: prompt-engineered workflows, automated refactors, infra-as-code and CI/CD templates, and LLM-aided profiling/debugging to deliver faster, production-ready integrations.
• Version control & CI/CD: Git (Bitbucket or GitHub), automated builds/tests/deploys.
• Strong debugging, logging, and production troubleshooting skills.

Nice-to-Have

• Salesforce, Blackbaud, or other CRM integration experience.
• Experience with message queues (RabbitMQ, SQS) and caching (Redis, Varnish).
• Familiarity with data warehouses (BigQuery, Snowflake).
• Experience with security / PII handling, GDPR/CCPA considerations.
• Unit/integration testing frameworks (PHPUnit, Jest, Pytest).
• Client-facing: explain technical choices clearly to non-technical stakeholders.
